Done 2 ways.
I cut the cabbage in half and then cut out some of the core.
I know, I know.... you're like - "wha-ev-vah, get to the bacon part!"
Cut the cabbage in to wedges place on parchment
or foil lined cookie sheet. I LOVE parchment!
Drizzle with Balsamic Vinegar.
Pop in a 350 oven for about 20-30 mins, until you've reached the doneness you like. Ilike mine with a soft crunch. Then I crank up the oven and BROIL for about 5 minutes, until there is slight charring.
